CYCLE AND BALANCE OF NUTRITION ELEMENTS IN AGRICULTURAL CENOSIS OF THE KASHKA-DARYA RIVERSION BASIN
Keywords:
Balance, a typical serozem soil, nutrient elements, winter wheatAbstract
It was established that under cotton, grown on newly irrigated typical serozem soils balance of nitrogen and phosphorus formed as a positive, income exceeds output. A potassium balance is negative, so introduction of potassium fertilizers does not match the required norms, which makes it necessary to review the norms of potassium fertilizer application. On the irrigated typical serozem soils under cotton nitrogen balance is positive, but phosphorus and potassium balance is negative. Under winter wheat nitrogen and potassium balance is negative, and balance of phosphorus is slightly positive. In general, removal of the nutrient elements exceeds the refund
